Full fill the environmental emissions needs new diesel particulate filter materials and new production processes developed. There are several filter material exist in the DPF market. Porous Si3N4 investigated considering the performance and structural properties. Carbothermal reduction and nitridation of silicon nitride(CRNSN) method and reaction bonding(RBSN)method combined. C/SiO2 ratio, quantity of Si3N4 additive, effect of starting raw materials and sintering additives type determined and porous silicon nitride filters produced. Pressure drop tests, permeability and soot loading tests made to the developed porous Si3N4 Ceramic filter. With using this two method, mechanical and filtering properties of porous silicon nitride developed with acceptable cost. Regarding the experimental work, pore size and distribution are more important than porosity volume. Pore size and distribution directly related with the filter performance. Microstructure is key point of the mechanical properties

In this study, it was aimed to develop a less costly fast double firing wall tile composition by using a dry grinding system. For this, the effect of 3 clays, Na-Feldspar and temperature on the properties of the final tile was investigated by factorial experimental design. In the experiment, an experiment with 24 31 general factors was designed, the effects of 5 main factors and their interaction with each other were examined. The significance tests of the hypotheses were made according to the significance level of a=0.05. Shrinkage, water absorption, density, porosity and strength tests were carried out on the samples produced from the prepared recipes and mineralogical and phase analyzes of the samples were made with SEM and XRD. The data obtained at the end of the experiments were analyzed with the MINITAB 14 package program and the results were examined.
